No they cant earn money daily from the crypto currency but on an average people do earn sufficient enough money on monthly basis. Thus, for some people it is far easy to earn money that way but its not that easy for some like me! Im not expert in all the stuff around here. May be be I can earn from the signature campaign all the time but trading, gambling and most of the ways here are not an option for me. So surely crypto currency doesnt fit for everyone here.
